PEORIA — An update on the leave requested by former Charter Oak Primary School Principal John Wetterauer:

It’s a medical leave on advice of his physician, according to Wetterauer’s attorney Nile Williamson. Wetterauer did not want to release any other information about his health, Williamson said.

Wetterauer has been at the center of the controversy that erupted after Peoria School District 150 began investigating how standardized tests were administered to Charter Oak special education students over a five-year period.

He had been scheduled to report Monday to Woodruff Career and Technical Center as “principal on special assignment,” a transfer District 150 board members approved as a result of the investigation. But he asked to be placed on leave Friday afternoon, three days before he was to report to Woodruff.

“He has a significant number of sick days,” Williamson said.

Williamson also wanted to make it clear that he was not satisfied with the district’s decision to reassign his client to a different school, as was stated in the Journal Star earlier.

However, a legal action could ensue if the district declines Wetterauer’s request for medical leave, Williamson said.

That’s unlikely, said District 150 spokesman Chris Coplan.

The board would approve Wetterauer’s request as a procedural matter when it accepts the district’s human resources report, Coplan added.

Wetterauer — who earned about $84,500, not including benefits, according to the district’s 2013-14 salary schedule — had been on paid leave since December. The district’s investigation alleged he failed to train teachers in how to properly administer the Illinois Standards Achievement Test to special education students.

After a series of board meetings packed with Wetterauer supporters pleading for his reinstatement to Charter Oak, board members unanimously approved reassigning him and disciplining four Charter Oak special education teachers.
